Who Is Spider-Man: Far From Home's Mystery Hero?
1. Doctor Strange
Doctor Strange might be a bit of dustcicle at the moment as well, but he has a whole lot more in common with the wall-crawler than fans would perhaps think.
One of the most interesting things about Infinity War was the dynamic shared between Tony Stark and Benedict Cumberbatch's Stephen Strange. The man of science meeting the man of magic provided one of the most refreshing dynamics in the film, with both leaders butting against each other on account of their preeminence in their given field.
Peter, at the time, was caught somewhat in the middle - but he still displayed a certain admiration for the Sorcerer Supreme. It's a world he's unfamiliar with, but willing to explore all the same. And with Cumberbatch's character one of the more likely choices to take over as a leading Marvel figure in the wake of Downey Jr.'s impending departure, having him pair with Peter would actually make a whole lot of sense.
There's more though. Mysterio is an illusionist who prides himself on his ability to manipulate and deceive; he's pretty much the antithesis of Strange, who engages with the mystic arts in order to protect the very fabric of existence. Throw in all the talk of alternate dimensions, Peter being thrust out of his comfort zone again and Mysterio's skills contrasting greatly with Strange's, and you have the set-up for the perfect Spidey team-up.
That is, if Cumberbatch actually returns...
